The SARE/ACE Project Summaries mention a potato project in Idaho led by Jerry Stark finding that "Sudangrass green manure grown prior to potatoes reduced Verticillium wilt by 60% and increased potato yields by as much as 30% compared with fallow treatments." Any other info? The person who asked me is considering planting olives in a cotton field that has a Verticillium problem, and he's looking for nonchemical ways to reduce the problem first. He asked specifically about cover crops, but I suppose other approaches would be of interest, too. Jill Auburn SAREP, Univ Calif jsauburn@ucdavis.edu
